Monograph: Performing the Assessment of Neuromuscular Maturity

Posture

Total body muscle tone is reflected in the infant's preferred posture at rest and resistance to stretch of individual muscle groups....(more)

Wrist flexibility and/or resistance to extensor stretching are responsible for the resulting angle of flexion at the wrist....(more)

This maneuver focuses on passive flexor tone of the biceps muscle by measuring the angle of recoil following very brief extension of the upper extremity...(more)

This maneuver assesses maturation of passive flexor tone about the knee joint by testing for resistance to extension of the leg... (more)

This maneuver tests the passive tone of the flexors about the shoulder girdle...(more)

This maneuver measures passive flexor tone about the pelvic girdle by testing for passive flexion or resistance to extension of posterior hip flexor muscles...(more)
